But if you're expecting his foe General Zod (Michael Shannon) to whip out a stick of kryptonite, think again: Superman's ultimate weakness in "Man of Steel" is … (wait for it)… his own confusion and sense of isolation.

An origin story that will take place, in part, on Superman's home planet of Krypton, Cavill insists the "human element" is the focus of the Zack Snyder-directed soon-to-be summer action blockbuster. "Growing up being so very different and not knowing why… that would be petrifying and lonely," the 30-year-old leading man told F*** magazine (in their latest issue) of the new iteration of his character.

"There's a very real story behind the Superman character," Cavill said, explaining that everyone's goal has been to explore the difficulties his character faces as a result of having multiple identities – including his birth name Kal-El and his alter ego Clark Kent.

"He's alone and there's no one like him," Cavill said of Superman's vulnerabilities in "Man of Steel." "That must be incredibly scary and lonely, not to know who you are or what you are, and trying to find out what makes sense. Where's your baseline? What do you draw from? Where do you draw a limit with the power you have? In itself, that's an incredible weakness."

Is Zod going to add psychological warfare to his arsenal against Superman? We'll find out when "Man of Steel" flies into theaters on June 14.
